3.3 COMPASS CALIBRATION
3.3.1 Principles of Compass Calibration (Super Halcyon 3
& Halcyon 2000 Compasses)
B&G's Autoswing Compasses contain software that allows them to
record the magnetic fields in the yacht that are causing the
deviation errors. It calculates the corrections every time the boat
completes a 540° turn - Super Halcyon 3 or 360
? turn - Halcyon
2000, provided the following conditions are met:
(a) The 540° turn - Super Halcyon 3 or 360 ? turn -
Halcyon 2000 is completed in the same direction.
(b) The rate of change of heading does not exceed 3°/s;
i.e. the turn should take about 3 minutes to complete.
(c) The rate of change of heading must not fall below 0.2
of a degree per second during the 540° turn - Super
Halcyon 3, i.e. the 540° turn must not take longer than 45
minutes.
